75mph OK with a roof rack?

I'm getting a new car soon and have been thinking about giving a roof rack a try instead of dealing with a trunk rack like I have with my current car (no trailer hitch availible). Is 75mph doable, or is that pushing it? Most of the races I enter during the season are 2 hours or so away, so I'd like to be able to crusie at 70+ since it's a lot of highway driving. I had a thule rack in mind that mounts via the front wheel fwiw, but haven't committed to a particular model yet.

I agree. However be prepared for bad gas mileage. And for bugs all over your bike

Don't forget to take the computer and bottles off the bike.
Must be a pretty small engine to mess up the gas that bad.
I use an Astro Van. the bikes stay clean.
Lots of room for other people.
Lots of room for gear.
Lots of room to sleep if needed.
Better still... American made.

American made - spoken like a true Canukian!

I've hauled canoes at 70+ and wondered if the guy behind questioned my tie down methods!

Drive I-95 at 70 mph on a weekday, especially at commte time, and you'll get run over. My son had to take a class when he got a speeding ticket and the VA state police said the average speed on I-95 to Washington is 77 mph.

I installed a fairing with my Thule rack and while it reduced the noise, it didn't do anything for the bugs. I use a trunk rack now and no bugs at all.

My buddys' bikes have to deal with the bugs associated with a roof rack.

I wouldn't have it any other way.

It might be an old wives tale or something that ceased to be a problem a decade or more ago, but the only bad things I've heard about transporting bikes on a roof rack is the 75mph wind can literally blow some grease out of or at least towards the back of a cheap POS loose ball headset. Apart from that, the biggest problem is forgetting about the bikes when you pull into the garage. That's another reason my bike goes inside.

An empty roof rack can decrease gas mileage by 12% at 55 mph. A bike on the rack is a huge sail and can reduce the mileage by 27% at 55. The faster you go, the worse it gets...simple aerodynamics.

Carrying bikes inside is better. Carrying them on the back is less bad than a roof rack.

Are you sure there are no hitches available for your new car? Just because a car is not rated to tow does not mean it cannot have a hitch installed. Back when I was a starving college student, I had a POS Hyundai Accent econobox, and that is the last car I would expect to be able to put a hitch on. Lo and behold, there is a 1.25" hitch available for it at U-Haul, cost me $160 installed. I've used it for years to lug my bike around until I finally upgraded to a better car.

Especially on a new car, I would avoid a roof rack-- You WILL cause a lot of dings and scratches on your new car while trying to mount and dismount the bikes from the roof.

Nope! American made. But the income is going to pay for the roads in the US (Where most of my family lives). I will ride on the roads and bike trails and parks in the U.S. during my vacations.
Very unlikely I will ride on any roads in Aisia.
Keep my money on this side thanks.

do not drive into a parking deck with it on top. i remember this day like it was yesterday. i transferred colleges and it was the first day of class. i had my bike on the roof and forgot. i headed into the parking deck and these two really hot girls were waving at me like crazy. i just began to think about how friendly the girls were at my new school. just about then i heard the a slam, boom, scratch, and bang. i immediately realized what i had done. nothing is more embarrassing on your first day at a new college and having two hot girls helping you load your rack and bike (in pieces) into the back seat of your car. the only good thing was one of the girls turned out to be in my program and always partnered up with me when we needed partners. at least i made a friend that day.

There is no reason your roof will get dinged up. I can easily lift our tandem onto our roof rack with damaging anything. If I had a tall vehicle I might need a short step stool, bit it is not difficult to be careful. I find my mileage is down about 10% with tandem in place at 70+ mph.

When we go on road trips with the kids, we have four touring kayaks and two mountain bikes up on top of our Honda Odyssey. Full width (78") bars, with the bike racks that grab the downtube. I use a 2' cam strap and a bungee for insurance because the jaws don't grab oversized downtubes all that well. Have driven hundres of miles both at freeway speeds and through the mountains like this and haven't lost a bike or kayak (from this setup anyway!). It looks precarious though, because the bikes are actually on the part of the rack that extends past the edge of the vehicle -- so they sort of tilt to the outside!

Next time we get a new car, I hope to convince my wife that a trailer is a better option though. We only load up this heavily for a couple trips each year, so we could get by with a smaller car most of the time.

When we do have the Ody loaded up like that, we also have the back loaded with camping gear, kayaking gear and paddles, two more bikes, food for 10 days or so, and sometimes a dog crate! We're like the Beverly Hillbillies goign down the road.

You have to be really lacking in the situational awareness department to do that, sorry. I read of that happening, and the only thing I have to say is to do it you have to be downright clueless.

I run a 4 bike Yakima roof rack on a Ford Focus. It costs 2mpg, and the bikes stay a LOT cleaner on the roof than they do in the rear, where the negative pressure deposits ALL the road crap on the bikes.
